Fla. Admin. Code Ann. R. 62-610.563 - Waste Treatment and Disinfection
(1) Rule
62-610.563, F.A.C., defines two
levels of treatment and disinfection: "principal treatment and disinfection,"
and "full treatment and disinfection." These two levels of treatment and
disinfection, or specific components of these levels of treatment and
disinfection, shall be applied to ground water recharge. Treatment and
disinfection requirements for potable reuse projects are established in Chapter
62-565, F.A.C.
(2) Principal
treatment and disinfection requirements.
(a)
Preapplication waste treatment shall result in a reclaimed water that meets, at
a minimum, secondary treatment and high-level disinfection. The reclaimed water
shall not contain more than 5.0 mg/L of total suspended solids before
application of the disinfectant.
(b) Filtration shall be provided for total
suspended solids control. Chemical feed facilities for coagulants, coagulant
aids, or polyelectrolytes shall be provided and maintained. Such chemical feed
facilities may be idle if the reclaimed water limitations are being achieved
without chemical addition. Filtration is an important component of the
wastewater treatment facility. By removing TSS before disinfection, filtration
serves to increase the ability of the disinfection process to inactivate virus
and other pathogens. Filtration also serves as the primary barrier for removal
of protozoan pathogens (Cryptosporidium, Giardia, and others). Addition of
chemical coagulants generally increases the effectiveness of pathogen
removal.
(c) Total nitrogen shall
be limited to 10 mg/L as nitrogen as a maximum annual average limitation.
Monthly average and single sample permit limitations shall be established using
the multipliers in subparagraph
62-600.740(2)(b),
F.A.C. For surface water discharges, WQBELs established under Chapter 62-650,
F.A.C., may place additional limitations on nitrogen or other
parameters.
(3) Full
treatment and disinfection requirements.
(a)
For non-potable reuse projects, principal treatment and disinfection
requirements described in subsection
62-610.563(2),
F.A.C., shall apply, unless they are less stringent than the requirements for
full treatment and disinfection.
(b) Drinking water standards.
1. Wastewater treatment facilities shall be
designed and operated to meet the primary and secondary drinking water
standards established in Rules
62-550.310 and
62-550.320, F.A.C.
a. The parameters listed as primary drinking
water standards shall be applied as maximum single sample permit limits. The
primary drinking water standard for asbestos shall not apply. The primary
drinking water standards for total coliform shall be applied as the
disinfection standard as described in subsection
62-550.310(3),
F.A.C., except that public notification requirements shall not apply. The
primary drinking water standard for sodium shall be applied as a maximum annual
average permit limitation. The multipliers established in subparagraph
62-600.740(2)(b)
2., F.A.C., shall be used to establish maximum monthly and single sample
maximum permit limits for sodium.
b. Except for pH, the parameters listed as
secondary drinking water standards shall be applied as maximum annual average
permit limits. The multipliers established in subparagraph
62-600.740(2)(b)
2., F.A.C., shall be used to establish maximum monthly and single sample
maximum permit limits.
c. All pH
observations in the reclaimed water shall fall within the pH range established
in the secondary drinking water standards.
(c) Additional reductions of pollutants which
otherwise would be discharged in quantities which would reasonably be
anticipated to pose risk to public health because of acute or chronic toxicity
shall be required.
(d) Total
organic carbon (TOC) shall not exceed 3.0 mg/L as the monthly average
limitation. No single sample shall exceed 5.0 mg/L.
(e) Total organic halogen (TOX) shall not
exceed 0.2 mg/L as the monthly average limitation. No single sample shall
exceed 0.3 mg/L.
(4)
Treatment and disinfection requirements imposed by Rule
62-610.563, F.A.C., are additive
to other effluent or reclaimed water limitations imposed by other rules (such
as WQBEL limits designed to protect surface water quality, which are imposed by
Chapter 62-650, F.A.C.).
(5) All
ground water recharge projects regulated by Part V of this chapter shall
implement pretreatment programs in accordance with Rule
62-610.330, F.A.C.
(6) For injection projects requiring full
treatment and disinfection, the Department shall approve alternative TOC and
TOX limitations or shall approve inclusion of treatment technologies provided
at the point of ground water withdrawal as part of the multiple barriers
required by paragraph
62-610.563(3)(f),
F.A.C., if the applicant provides an affirmative demonstration of all of the
following in the engineering report:
(a) All
withdrawals of ground water for potable purposes within one mile of the
injection well are owned and operated by the applicant.
(b) Other parties are legally prohibited from
installing or operating potable water supply wells within one mile of the
injection well.
(c) Treatment
provided on water supply wells within one mile of the injection well includes
reverse osmosis or other processes that will serve as barriers for control of
organic compounds or pathogens.
(d)
The integrated treatment and disinfection system (wastewater treatment
facilities and water treatment facilities) provides a level of public health
protection equivalent to the full treatment and disinfection requirements in
subsection 62-610.563(3),
F.A.C.
